The encryption module possesses a set encryption key, the decryption module possesses a corresponding set decryption key, and if the file cannot be decrypted by using the set decryption key, the file is deleted from the second server.
Here, the set encryption key and the set decryption key may be symmetric keys or asymmetric keys.
Symmetric keys, i.e., the sender and receiver of a file, use the same key to encrypt and decrypt the file. Its most important advantage is that it is quick in encryption/decryption speed, suitable for encrypting large data volume file, but difficult in key management.
Asymmetric keys require the use of different keys to perform the encryption and decryption operations, respectively, one being publicly distributed, i.e., a public key, and the other being held in the user's own secret, i.e., a private key. The sender of the file uses the public key to decrypt and the recipient of the file uses the private key to decrypt. Public key mechanisms are flexible, but encryption and decryption speeds are much slower than symmetric key encryption.
By encrypting the file, the file can be prevented from being leaked in the transmission process, the risk of data loss is reduced, and the safety and reliability of the file are improved.
